Patent DE-3127892-A1 (DE)
Title: Vehicle seat with a rail guide which can be adjusted in the direction of travel and can be fixed at its extended length by a latching device
Inventor: WERNER UDO
IPC: B60N2/07
Filed: 1981-07-15
Abstract: The invention relates to a vehicle seat which can be adjusted in the direction of travel by a rail guide which can be fixed in its particular extended position by a latching device. The rail guide is assigned a shock absorption means which absorbs longitudinal shocks of the seat and can be put into effect and taken out of effect as desired by means of a switching device operable by a handle. The known vehicle seats of this type are too complicated and expensive with respect to the longitudinal shock absorption and switching and, moreover, also too bulky in their design in this respect. The invention solves this problem by a substantial saving on components and arrangement space by the handle for switching on and off the longitudinal shock-absorber free movement being mounted pivotably on a longitudinal rod, already present, of the shock absorption means and the release latch of the latching device, fixing the longitudinal extension of the rail guide, being directly locked in its one end position while in its other end position it releases this latching device. By virtue of this fact, already present components of the longitudinal shock absorption means and of the rail latching device of the longitudinal shock absorption means are used. A corresponding vehicle seat is thus simpler and more cost-effective in construction and, moreover, due to the twin functions of individual components, also less voluminous and, as a result, ultimately more suitable for the space available, which along the flank is restricted.

Title: Wind generator
Inventor: KLIEMT WOLFGANG
IPC: F03D13/10
Filed: 1981-08-01
Abstract: A wind generator consists of a support frame (1), a rotary stand (2) which is seated on the upper end of the support frame and has a lower part (15), which can be permanently connected to the support frame, and an upper part (17) which has a rotor shaft (18) and can rotate about a vertical axis (16) relative to the lower part, as well as a rotor (3) which is seated on said shaft and is provided with wind vanes (22). Such a wind generator is intended to be easy to assemble and maintain at low cost and to be economical. In order to achieve this, the wind generator can be constructed as a kit in which the wind vanes (22) of the rotor each consist of a support rod (23) held in a hub and of a sail-like covering (25) carried by said support rod. The sail-like covering (25) can be pivoted about the longitudinal axis of the particular support rod (23) and can have a torque applied to it which opposes the wind force around the axis of the support rod. The application of this torque can be performed using a tension spring, a leg spring or some other tension element which acts on the covering with a force which depends on the speed of the rotor. <IMAGE>

Title: Device for controlling a single-phase asynchronous motor with an electronic auxiliary phase
Inventor: BAUER ROLAND DIPL ING
IPC: H02P25/04
Filed: 1981-09-02
Abstract: The invention relates to a device for rotation speed control of single-phase asynchronous motors by varying the phase angle of the fundamental wave of the auxiliary phase current obtained by voltage wave gating. The invention is intended, in particular, to reduce the double cost for rotation speed regulation on the one hand and for producing a phase-shifted auxiliary phase current on the other hand. The regulation is based on the allocation of the optimum triggering angle for the voltage wave gating of the auxiliary phase current, in order to achieve the maximum motor torque for the respective rotation speed. The regulator causes the triggering angle to be reduced in the case of low motor rotation speeds and the triggering angle to be increased in the case of motor rotation speeds which are close to the synchronous rotation speed. The field of application is, in particular, drives for domestic appliances in which rotation speed regulation or control of the rotation speed is carried out in accordance with a specific program such as control of the starting of the spinning process in fully automatic washing machines, for example.

Title: Tensioning device
Inventor: GRUENEWALD GERHARD
IPC: B61B12/00
Filed: 1981-10-21
Abstract: The known tensioning devices comprise a plurality of tensioning cylinders which are incorporated into the pulling cable shafts running onto the drive wheel or off the drive wheel and have tensioning rollers and additional tensioning rollers which are stationary or form components of further tensioning cylinders. They require a large degree of space. The pulling cable is deflected many times. There is a high degree of cable wear. According to the invention, only a single tensioning cylinder (8) with tensioning rollers (12, 13) on one side is incorporated into the shafts (16, 17) of the pulling cable (1) which run onto or off the drive wheel (3). The tensioning cylinder housing (11) or the piston rod (10) can be displaced, as a function of the pulling direction, between fixed stops (23, 24) which are offset in the longitudinal direction of the tensioning cylinder (8). The constructional complexity is notably reduced. The cable wear is decreased and the useful life thus increased. The design is compact so that tensioning device (8, 12, 13) and pulling cable drive (4) can be constructionally combined. The tensioning device (8, 12, 13) can be operated in a suspended or horizontal position. <IMAGE>

Title: Heat exchanger for gases of widely differing temperatures
Inventor: ZACHERL ANTON
IPC: F28D7/06
Filed: 1981-11-20
Abstract: The present invention relates to a heat exchanger for conducting gases of widely differing temperatures whose cross-counterflow matrix, which is located in the hot gas flow, consists of separate tubes which are connected, on the one hand, to a first stationary pipe duct for the supply of compressed air into the relevant matrix channels and, on the other hand, to a second stationary pipe duct from which the compressed air heated up via the matrix is fed to a consumer, the two separate pipe ducts either being integrated in a common manifold or being formed from individual tubes arranged essentially parallel next to one another, the heat exchanger matrix or its relevant compressed air channel guides (tubes, hollow profiles) extending laterally projecting in a U-shaped fashion with respect to the tube or tubes. In order to eliminate the risk of cracks as a matter of priority, the present invention principally provides that the manifold or the individual tubes are essentially provided in the zones located outside the connecting regions of the heat exchanger matrix with hollow bodies which penetrate the relevant tube wall and are constructed in a closed fashion at the end guided into the tube interior, and in an open fashion at the end located on the side of the tube outer wall.

Title: Adjustable sighting-comb device for portable firearms, especially automatic pistols
Inventor: KORTH WILLI
IPC: F41G1/06
Filed: 1982-02-05
Abstract: In order, whilst ensuring a long lifetime, to allow a secure mounting of the sighting comb in the breechblock of a portable firearm, especially an automatic pistol, there is an adjustable sighting-comb device according to Figure 1, in which the sighting comb (7) is also inserted from above in a simple way into a milled-out portion (11) of the breechblock and is secured in the inserted position by a wedge body (10) guided movably in the breechblock (18). In the inserted position, the sighting comb (7) can engage with its lower end (26) into a recess (30) of the striking pin (5), in order to limit its displacement travel in the longitudinal direction in the bore (4) of the breechblock (18) under the effect of the spring (6). The wedge body (10) engages into an aperture of the sighting comb (7). The sighting comb can have threaded bores aligned in the transverse direction and intended for grub screws which are supported on the wedge body (10) on both sides of the latter, so that the sighting comb can be accurately adjusted transversely to the firing direction in relation to the wedge body and therefore in relation to the breechblock (18). <IMAGE>

Title: Impact mechanism for a poker vibrator for soil compaction
Inventor: HILBERT HELMUT DIPL ING
IPC: E02D3/054
Filed: 1982-02-12
Abstract: The impact mechanism driven by a motor with variable speed consists of a hollow cylinder (2) coaxially surrounding the drive shaft (1). A space section (5) with walls (6) is partitioned off from the bottom area of the hollow cylinder (2) in such a way that only a space (7) arranged eccentrically to the drive shaft (1) remains there. This space (7) merges at the top into the cylindrical space section (3) of the hollow cylinder (2). A free-flowing medium of high specific weight or balls of heavy metal, e.g. tungsten, with the addition of a lubricant, introduced into the eccentrically arranged space (7) for the most part rise up out of the eccentrically arranged space (7) into the cylindrical space section (3) of the hollow cylinder above it when the speed increases and then no longer act as an unbalancing agent, since they are uniformly distributed there around the axis of the drive shaft (1). The impact force of the impact mechanism is thus reduced as speed increases. <IMAGE>

Title: Arrangement for converting a measurement voltage to a constant amplitude whilst retaining its frequency
Inventor: PEUSER WOLFGANG DIPL PHYS DR
IPC: G01R19/00
Filed: 1982-02-17
Abstract: The subject matter of the application is a circuit arrangement which brings a measurement voltage UM, which is within a certain frequency band, for example the telephone transmission band, and arrives attenuated in dependence on frequency, to a constant amplitude whilst retaining its frequency. In a limiter circuit (1), the measurement voltage UM is first converted into a square wave voltage. A tracking filter of familiar construction, which here consists of a switched-capacitor low-pass filter (7) and a PLL (phase-locked loop) circuit (2) with a step-down stage (3) in the control loop, is controlled in its cut-off frequency in such a manner that the latter is in each case 1.28 times the measurement voltage frequency. The constant square wave voltage at the output of the step-down circuit (3), the frequency of which corresponds to the frequency of the measurement voltage for each control operation, is reshaped into the desired sinusoidal voltage by the switched-capacitor low-pass filter (7). Interfering components of the clock signal frequency controlling the low-pass filter (7) are suppressed by two low-pass filters (6 and 8). A further development contains a frequency discriminator (4) which is tuned to the range limits of the frequency band to be processed and the output signal of which is combined with the signal from the PLL circuit (2) in an AND circuit (5) so that this PLL circuit only becomes effective in the predetermined band. <IMAGE>

Title: Firing simulation method and a device for carrying it out
Inventor: GODA WILFRIED ING GRAD
IPC: F41G3/26
Filed: 1982-08-05
Abstract: A method and a device for simulating the firing of ballistic weapons, in which a reflective target is measured by means of laser pulses which are transmitted at the weapon end instead of an actual shot, and the accuracy of target tracking is assessed, and a hit or miss display controlled therefrom, are designed according to the invention for firing training on a weapon in which a fire-control computer calculates the angle of sight and lead angle and automatically sets the weapon, based on the signals from a target tracking sight and a target range finder using a high-power laser, such that the firing simulator is already carrying out an initial aiming point assessment at the time when the target range finder is triggered, produces a range echo signal, which can be processed by the fire-control computer, as a function thereof, measures the line of sight and lead angle setting, which is controlled to that effect by the fire-control computer, and uses the new target position produced in this case as the origin for the subsequent aiming point assessment until firing. The function of the target range finder and of the fire-control computer can thus be made use of in a realistic manner in the firing simulation without specifically adapted interfaces being required between the fire-control computer and the firing simulator.

Title: Device for producing a static contact seal with plastic deformation
Inventor: BABIAK PETER
IPC: F16J13/12
Filed: 1982-11-15
Abstract: The invention relates to a device for producing a static contact seal with plastic deformation between two annular end faces to be sealed off relative to one another, for example the rim of a vessel for accommodating irradiated fuel elements of nuclear reactors with an associated lid, using at least one so-called delta-shaped cutting edge. The aim of the invention is to bring about the closure and sealing of such a vessel in a particularly rapid and permanent manner. This is achieved by virtue of the fact that one element of the two parts to be sealed off relative to one another, e.g. the part with the cutting edge, is brought into contact with the other element, manufactured from softer material, with an energy or speed sufficient to permit plastic deformation, with permanent prestress. For this purpose the invention discloses a special device which can be inserted in the prestressed condition into the vessel, locked in the latter by rotation and released by subsequently rotating it further. The high prestress then ensures the desired sealing effect.
